This also suggests that the Borders app would be a way to read enTourage eBooks (and other Adobe Reader PDFs/ePubs) on the LCD side. Anyone care to try that out and post the results? (Don't export an existing PDF from your Library, though, as that's then just an unprotected PDF of images of pages...)

Doesn't appear to work. Obtaining epubs and pdfs can only be done with the browser and not the app far as I can tell. The app also does not seem to have any way to open files that are not listed in your Borders account, only find books and download them in an unknown proprietary format. In essence it seems like a clone of the Kindle android app.
